Description

Technical Field

[0001] This application relates to the field of scooter battery pack technology, and more particularly to a modular and replaceable scooter battery pack. Background Technology

[0002] Current electric scooter battery packs are typically fixed in place, mechanically connected to the scooter body via screws, clips, or other fasteners. However, replacing existing battery packs is cumbersome, requiring specialized tools for disassembly and assembly, is time-consuming, and is not suitable for non-professionals. Due to structural design limitations, it is difficult to achieve universal and modular deployment of battery packs across multiple models or platforms, thus limiting further improvements in maintenance and operational efficiency.

[0003] In view of the above problems, there is an urgent need to propose a modular and replaceable scooter battery pack that can enable quick disassembly and replacement of the battery pack while ensuring electrical connection and mechanical stability, thereby improving the ease of use and operational efficiency of the scooter. Utility Model Content

[0004] The purpose of this application is to overcome the shortcomings of the prior art and propose a modular, replaceable scooter battery pack.

[0005] This application is achieved through the following technical solution:

[0006] This application proposes a modular, replaceable scooter battery pack, comprising:

[0007] The scooter body has a mounting slot on it;

[0008] The battery pack can be placed in the mounting slot;

[0009] The top cover is fixedly connected to the battery pack. A locking groove is provided at each of the four corners of the top cover. When the top cover is placed in the mounting groove, the locking groove is connected to the mounting groove.

[0010] Four knob locking discs are located at the four corners of the mounting groove and are rotatably connected to the scooter body. The rotating ends of the knob locking discs form a locking structure for cooperating with the locking groove.

[0011] When the knob locking disc is rotated to the locked position, the locking structure is inserted into the corresponding locking groove to secure the top cover plate onto the scooter body.

[0012] When the knob lock is rotated to the unlock position, the locking structure disengages from the locking groove, allowing the top cover to be removed from the mounting groove, thereby enabling quick replacement of the battery pack.

[0013] In one embodiment of this application, the locking structure has an opening slot. When the knob locking disc is rotated to the unlock position, the opening slot communicates with the locking slot, so that the top cover can be removed from the mounting slot, thereby enabling quick replacement of the battery pack.

[0014] In one embodiment of this application, the knob locking disc is provided with a snap-fit ​​structure, and the scooter body is provided with a snap-fit ​​groove in the groove wall of the mounting groove. The snap-fit ​​structure can snap into the snap-fit ​​groove to prevent the locking structure from rotating.

[0015] In one embodiment of this application, the snap-fit ​​structure includes a connecting portion and a protrusion. The connecting portion is fixedly connected to the locking structure, and there is a circumferential gap between the connecting portion and the locking structure. The connecting portion can move toward or away from the center of the locking structure, and the protrusion is provided on the side of the connecting portion away from the locking structure.

[0016] When the protrusion is in contact with the inner wall of the mounting groove, the protrusion pushes the connecting part to move toward the center of the locking structure so that the locking structure can rotate.

[0017] When the protrusion engages with the locking groove, it prevents the locking structure from rotating.

[0018] In one embodiment of this application, the knob locking disc further includes a grip portion located at the top of the locking structure, so as to allow the locking structure to be rotated by hand.

[0019] In one embodiment of this application, the knob locking disc further includes a rotating shaft, which is rotatably connected to the scooter body and fixedly connected to the locking structure.

[0020] In one embodiment of this application, the top cover is provided with a pull ring at its top end to allow the top cover to be removed from the mounting groove.

[0021] In one embodiment of this application, there are two pull rings, which are disposed at the top ends of the top cover plate.

[0022] Compared with the prior art, the beneficial effects of this application are:

[0023] The scooter body has mounting slots where the battery pack can be placed. A top cover is fixedly connected to the battery pack, and each of the four corners of the top cover has a locking slot. When the top cover is in the mounting slot, four rotary locking discs are located at the four corners of the mounting slot and rotatably connected to the scooter body. The rotating ends of the rotary locking discs form a locking structure for engaging with the locking slots. When installing the battery pack, the user simply places it in the mounting slot, positions the top cover, and then rotates each locking disc to the locked position, inserting the locking structure into the locking slot and securely locking the battery pack to the scooter body. Conversely, when replacing the battery pack, simply rotate the rotary locking discs to the unlocked position, disengaging the locking structure from the locking slot, and the entire battery assembly can be easily removed. Thus, by placing the rotary locking discs at the four corners of the battery mounting location and utilizing the rotatable locking structure in conjunction with the cover's locking slots, tool-free quick installation and removal of the modular, replaceable battery pack is achieved, greatly simplifying the battery replacement process.

[0038] Please refer to Figures 1 to 4 This application proposes a modular replaceable scooter battery pack 10, including a scooter body 100, a battery pack 200, a top cover 300, and four knob locking discs 400. The scooter body 100 is provided with a mounting groove 110. The battery pack 200 can be placed in the mounting groove 110. The top cover 300 is fixedly connected to the battery pack 200. A locking groove 310 is provided at each of the four corners of the top cover 300. When the top cover 300 is placed in the mounting groove 110, the locking groove 310 is connected to the mounting groove 110. The four knob locking discs 400 are respectively provided at the four corners of the mounting groove 110 and are rotatably connected to the scooter body 100. The rotating end of the knob locking disc 400 forms a locking structure 410 for cooperating with the locking groove 310.

[0039] When the knob locking disc 400 is rotated to the locked position, the locking structure 410 is inserted into the corresponding locking groove 310 to lock the top cover 300 onto the scooter body 100.

[0040] When the knob lock disc 400 is rotated to the unlock position, the locking structure 410 disengages from the locking groove 310, so that the top cover 300 can be removed from the mounting groove 110, thereby enabling quick replacement of the battery pack 200.

[0041] Specifically, the scooter body 100 is provided with a mounting slot 110 for accommodating the battery pack 200, which can be directly embedded into the mounting slot 110. A top cover plate 300 is fixedly connected to the top of the battery pack 200, and locking slots 310 are provided at the four corners of the top cover plate 300. When the top cover plate 300 is installed in the mounting slot 110 of the scooter body 100, each locking slot 310 is aligned with a knob locking disc 400 provided in the mounting slot 110. The knob locking disc 400 is rotatably connected to the scooter body 100, and the knob locking disc 400 is provided with a locking structure 410 that can be engaged with the locking slot 310. When installing the battery pack 200, the user simply places it into the mounting slot 110, and after the top cover 300 is in place, rotates each locking disc to the locked position, causing the locking structure 410 to insert into the locking groove 310, thereby securely locking the battery pack 200 into the scooter body 100. Conversely, when replacing the battery pack 200, simply rotate the knob locking disc 400 to the unlocked position, causing the locking structure 410 to disengage from the locking groove 310, allowing for easy removal of the entire battery pack 200.

[0042] In this way, by placing the rotary locking disc 400 at the four corners of the battery installation location and utilizing the rotatable locking structure 410 in conjunction with the cover plate locking groove 310, tool-free quick installation and removal of the modular replaceable battery pack 200 is achieved, greatly simplifying the battery replacement process. At the same time, this structural design possesses excellent mechanical stability, avoiding the problem of easy damage to traditional clips or screws during frequent operation, thus improving product reliability and service life.

[0043] In one embodiment, the locking structure 410 has an opening slot 411. When the knob locking disc 400 is rotated to the unlock position, the opening slot 411 is connected to the locking groove 310 so that the top cover 300 can be removed from the mounting groove 110, thereby enabling quick replacement of the battery pack 200.

[0044] Specifically, the locking structure 410 of the knob locking disc 400 has an opening slot 411. When the knob is rotated to the unlock position, the opening slot 411 communicates with the locking groove 310 on the top cover 300, forming a through channel. Specifically, when the user rotates the knob to the unlock angle, the opening slot 411 of the locking structure 410 aligns with the locking groove 310 on the cover, releasing the latching state on the top cover 300. This allows the top cover 300 to be lifted directly, thus removing it along with the battery pack 200 from the mounting slot 110, completing the battery removal and replacement. This avoids the problem of needing to pry or perform additional operations after the knob is unlocked in traditional structures, achieving clear indication of the structural status and mechanical linkage control.

[0045] In one embodiment, the knob locking disc 400 is provided with a snap-fit ​​structure 420, and the scooter body 100 has a snap-fit ​​groove 120 in the groove wall of the mounting groove 110. The snap-fit ​​structure 420 can snap into the snap-fit ​​groove 120 to prevent the locking structure 410 from rotating.

[0046] Specifically, the mounting groove 110 of the scooter body 100 has a corresponding locking groove 120 on its groove wall. The locking structure 420 can be inserted into the locking groove 120 when the knob locking disc 400 is rotated to the locked position, thereby forming a locking engagement. After the knob completes the locking action, this structure can limit the knob locking disc 400 axially or circumferentially, preventing it from loosening or rotating due to vibration or long-term use, and ensuring that the locking structure 410 remains in the locked state.

[0047] In one embodiment, the snap-fit ​​structure 420 includes a connecting portion 421 and a protrusion 422. The connecting portion 421 is fixedly connected to the locking structure 410, and there is a circumferential gap between the connecting portion 421 and the locking structure 410. The connecting portion 421 can move toward or away from the center of the locking structure 410, and the protrusion 422 is provided on the side of the connecting portion 421 away from the locking structure 410.

[0048] When the protrusion 422 is in contact with the inner wall of the mounting groove 110, the protrusion 422 pushes the connecting part 421 toward the center of the locking structure 410 so that the locking structure 410 can rotate.

[0049] When the protrusion 422 engages with the locking groove 120, it prevents the locking structure 410 from rotating.

[0050] Specifically, the snap-fit ​​structure 420 includes a connecting portion 421 and a protrusion 422. The connecting portion 421 is fixedly connected to the locking structure 410 of the knob locking disc 400, and a certain circumferential distance is reserved between it and the locking structure 410, so that the connecting portion 421 has a certain radial movement capability. The protrusion 422 is located on the side of the connecting portion 421 away from the locking structure 410. When the knob is rotated, if the protrusion 422 is in contact with the inner wall of the mounting groove 110 of the scooter body 100, the protrusion 422 pushes the connecting portion 421 to shift towards the center of the locking structure 410, so as not to affect the normal rotation of the knob; while when the protrusion 422 is engaged with the snap-fit ​​groove 120, the connecting portion 421 cannot shift inward due to the restriction, thereby restricting the locking structure 410 from continuing to rotate, and realizing the effective limiting of the knob locking disc 400. In this way, the top cover plate 300 can be fixed to prevent vibration; and the locking groove 310 and the opening groove 411 can be kept in continuous communication.

[0051] In one embodiment, the knob locking disc 400 further includes a grip portion 430, which is disposed at the top of the locking structure 410 so as to allow the locking structure 410 to be rotated by hand.

[0052] Specifically, the grip part 430 is located at the top of the locking structure 410. When the user is installing or removing the battery pack 200, he or she can directly rotate the grip part 430 to drive the locking structure 410 to complete the locking or unlocking action.

[0053] In one embodiment, the knob locking disc 400 further includes a rotating shaft 440, which is rotatably connected to the scooter body 100 and fixedly connected to the locking structure 410.

[0054] Specifically, the rotating shaft 440 is rotatably connected to the scooter body 100 and fixedly connected to the locking structure 410. The rotating shaft 440 is preferably vertically positioned at the bottom of the mounting groove 110, forming a rotational engagement with the scooter body 100 via bearings. The user rotates the rotating shaft 440 by turning the grip part 430 of the knob, thereby enabling the locking structure 410 to be inserted into or disengaged from the locking groove 310. Since the locking structure 410 and the rotating shaft 440 are integrally connected, stability and precise positioning during rotation are guaranteed.

[0055] In one embodiment, the top cover 300 is provided with a pull ring 320 at its top end to allow the top cover 300 to be removed from the mounting groove 110. There are two pull rings 320, which are located at both ends of the top of the top cover 300.

[0056] Specifically, the top cover 300 has two pull rings 320 at its top end, which are respectively located at both ends of the top cover 300. When the user needs to replace the battery pack 200, he / she can directly grab the two pull rings 320 and apply force to lift the top cover 300 together with the battery pack 200 from the mounting slot 110.

[0057] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
